Given:

The coordinates of point P are (-5,4).

Point P is reflected over the x-axis.

To find:

The new coordinates after the reflection.

Solution:

If a point is reflected across the x-axis, then the rule of reflection is:

$(x,y)\to (x,-y)$

Using this rule, we get

$P(-5,4)\to P'(-5,-4)$

The new coordinates of point P after the reflection over the x-axis are (-5,-4).

Therefore, the correct option is B.
